The tube cane is sold by the 1/2 pound. We sort it in bags of 10-10.5mm diameter and 10.5-11mm diameter. Pisoni is the hardest of the cane we offer with Alliaud right behind. Ghys is on the softer side. Gonzalez is a very dense cane from Argentina, making reeds with a very focused sound. Rigotti is a medium cane.
